Abstract

PURPOSE:To simplify the assembly and disassembly of an apparatus and facilitate washing thereof, by constructing the apparatus in such a manner that a plate containing superconducting material is put in a container and agitation is carried out by the magnetic field generated around the plate and irradiation with light which changes a superconducting state of material into a normal conducting state. CONSTITUTION:When a container 5 containing a fluid 6 is placed on a magnetic field generator 2 and a magnetic field is generated around a disc 1, the disc 1 consisting of superconducting material is caused to float up along a rod 7 to the head 7a thereof by Meissner effect. In this state, when an irradiation device 3 provided outside the container 5 is put on, the portion of the disc 1 which has been irradiated changes from a state of superconduction to a state of normal conduction, wherein said portion looses buoyancy by Meissner effect and tilts downwardly as illustrated by the arrow 9. And when the irradiation device 3 is put off, Meissner effect occurs again, during which differences in the level of the fluid 6 instantaneously occurs, causing agitation of the liquid 6 in the container 5 whenever the tilting motion of the disc 1 occurs.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a stirring device such as a mixer.

BACKGROUND OF THE INVENTION Conventionally, stirring devices such as mixers have been comprised of a main body, which is a driving section containing an electric motor, and a removably mounted container on the top of the main body. A stirrer blade is provided in the container and rotates while being connected to the driving rotation shaft of the motor, and the stirring blade is driven by transmitting the driving rotational force of the motor through a mechanical drive transmission means. The stirrer was rotated by rotating the drive shaft and connecting the stirrer blades supported by the container to the drive shaft.

Problems to be Solved by the Invention In such conventional stirring devices, since the stirrer is axially supported by the container, it cannot be easily removed, and when cleaning the container, it is difficult to remove the stirrer from the corner. It may not be possible to thoroughly clean all the parts, or it may be dangerous. In addition, mechanical means are required to connect the motor drive shaft and the stirring blade, making the configuration complicated. It had a T jlfJ point.

Means for Solving the Problems The present invention provides a container containing a fluid, a plate containing a superconducting material that can be inserted into the container, an irradiation device that irradiates the plate with light, and a magnetic field around the plate. This is a stirring device equipped with a magnetic field generating device that generates.

Operation According to the present invention, a plate containing a superconducting material is placed in a container containing a fluid. When a magnetic field generator generates a magnetic field around the plate in the container, the plate floats in the fluid due to the Meissner effect.

When this floating plate is irradiated with light, the portion of the plate irradiated with light changes from a superconducting state to a normal conducting state. As a result, the part irradiated with light loses its repulsive force against the magnetic field, and due to gravity, this part becomes suspended in a downwardly inclined manner. When the light is no longer irradiated, this part returns to a superconducting state and becomes horizontal again due to the Meissner effect. In this way, depending on whether or not light is irradiated, the board will tilt or become horizontal. This tilting movement of the plate agitates the fluid within the container.

An embodiment diagram shows a cross-sectional configuration diagram of an embodiment of the stirring device of the present invention.

1 is a disk made of superconducting material, 2 is a magnetic field generator that generates a magnetic field, 3 is an irradiation device that irradiates light onto the disk 1, and 4 is the light emitted from the irradiation device 3, and further controls the amount of light. It is a light source control device.

A disk 1 made of a superconducting material has a hole 1a in its center, and a stake 7 passing through the hole 1a is simply fixed to the container 5 by a threaded portion 7b. Therefore, no matter how the disk 1 moves, the disk 1 is fixed approximately at the center of the container 5 by the stake head 7a and the spring 8.

Further, the magnetic field generator 2 and the container 5 are configured to be detachable, and by removing the stake 7 with the screw portion 7b, the disk l can be attached to the container 5.
FiiT can be easily taken out.

In addition, there are two superconducting materials contained in the disk l, for example, Y-Ba-
Cu-0 (oxide consisting of yttrium, barium, in), SI・-13a-Y-Cu-0 (oxide of strontium, barium, yttrium, copper),
E r-Ba-Cu-0 (Erbiuno,.

It is possible to use oxides such as oxides such as oxides such as oxides such as oxides consisting of halium A and ``Ai''.

The magnetic field generating device 2 only needs to generate a magnetic field that causes the disk 1 to levitate within the fluid 6, and is constituted by, for example, a permanent magnet, an electromagnet using a coil, or the like.

! ! The radiation device 3 only needs to have a wavelength that allows the transmitted light to transfer the superconducting material contained in the disk l to the normal conduction state, and for example, an infrared laser transmitter or the like can be used. In addition, the irradiation device 3 is placed at a position where the emitted light can be irradiated onto the disc 1.
may be placed inside the container 5, but this example shows a case where it is placed outside the container 5.

The container 5 can be made of various materials as long as it is not eroded by the fluid 6. However, if the irradiation device 3 is installed outside, at least the part of the container 5 that corresponds to the optical path should be made of a light-transmitting material, such as glass. Use. Further, when a metal material such as copper is used for the container 5, the magnetic field generating device 2 is preferably installed inside the container 5 in order to block the magnetic flux.

The operation of the stirring device of this embodiment configured as described above will be explained below.

First, the container 5 containing the fluid 6 is placed on the magnetic field generator 2. Next, when a magnetic field is generated around the disk 1 by the magnetic field generator 2, the disk 1 floats along the pile 7 due to the Meissner effect since it is made of a superconducting material. This floating height is limited by the head 7a of the pile 7 and the spring 8.

As shown in Figure 1QI, when the light Q1 device 3 attached to the outside of the container 'a5 is turned on, the portion of the disc covered by the cover (in the figure, the left side of the disc 1) changes from a superconducting state to a normal conductive state. changes to the state of The part that has changed to normal conductivity loses its buoyancy due to the Meissner effect, so the normal conduction part (in the figure,
The superconducting portion (the right side of the disk 1 in the figure) is tilted upward according to the arrow 10. Corresponding to this tilting movement of the disk 1, the fluid 6 in the container 5 also
There is a momentary difference in height according to arrows 11a and 12a,
The fluid 6 is stirred in an attempt to regain its horizontal surface. Next, when the irradiation device 3 is turned off, the Meissner effect occurs on the surface of the disk 1, and the disk 1 is pressed toward the head 7a of the pile. At this time, the fluid 6 instantaneously makes a height difference in accordance with the arrows 1II) and 12b, contrary to the navigation, but the fluid 6 is similarly stirred as it tries to regain its horizontal surface. therefore,
Every time this tilting movement of the disk l occurs, the fluid 6 in the container 5 is stirred.

In this embodiment, the disk 1 only needs to contain a superconducting material and generate a force for floating in the fluid due to the Meissner effect.
In addition to superconducting materials, one or more types of resin materials such as polyethylene, metal materials such as copper, etc. can be used in combination.

Further, although the disk 1 is a flat plate, in order to promote stirring of the fluid 6, irregularities may be present on the surface.
The shape also does not have to be limited to a circle.

Furthermore, in this embodiment, one illumination device 3 is used, but it is possible to install a plurality of illumination devices and individually irradiate multiple parts of the disk 1.
It is also possible to stir the fluid 6 in the container 5 by making the inclination of the disk l complicated.

Effects of the Invention As described above, according to the present invention, there is no need for a means for connecting the stirring blade and the motor that drives the stirring blade, so the configuration is simplified and the stirring blade can be used easily. Plates made of certain superconducting materials can be easily removed. Also,
It is extremely effective in practical terms, as it can thoroughly clean every corner of the container.
